Melt the white candy melts per the instructions on the bag.
Pour the melted chocolate onto a silpat mat or some waxed paper. I poured mine onto a jelly roll sized pan
Melt the blue candy melts per the instructions on the bag. I think I used half of the bag.
Drop melted blue chocolate by the spoonful all over the white chocolate. Leave some room between drops.
Take a toothpick and pull the blue chocolate into the white chocolate by making lines all the way around the circle of blue chocolate to resemble Cookie Monsters fur.
Let set in the refrigerator for 15 minutes.
Melt about a cup of the black candy melts per the instructions on the bag.
After the bark has set, take a toothpick and dip into the black melted chocolate and draw mouths on the Cookie Monster faces.
With some blue melted chocolate, place the googly eyes on Cookie Monster. We tried to make them cock-eyed just like his!
Again with some blue melted chocolate, dip a mini chocolate chip cookie into the blue chocolate and place the cookie near Cookie Monster's mouth.
Chill in the refrigerator until completely set.
After it has hardened, cut or break the bark around the Cookie Monster faces.
